Freeze Prevention Devices
This unit comes equipped with heater blocks to
prevent freezing which can damage the heat
exchanger. For this freeze prevention system
to operate there has to be electrical power to
the unit. Damage to the heat exchanger
caused by freezing due to electric power
outage is not covered under warranty.
The freeze prevention devices will not work
if the electrical power source is
disconnected.
The unit has been rated for temperatures down
to 5º F (-15º C) in a wind free environment.
The wind chill factor will cause the unit to
freeze at temperatures above 5º F (-15º C).
Do not install the water heater in an area with
extremely cold weather, this will void warranty
and Takagi-USA will not be held responsible
for any damage occurring from such
environment. For this purpose a back flow
prevention kit (Part TK-TV03) is highly
recommended for areas with freezing weather,
to prevent freezing air from entering through
the exhaust venting when the water heater is
on standby which can damage the heat
exchanger.
CAUTION:
The pipe heaters are located on
the MOBIUS Water Heater only. Any hot or
cold water pipes located outside of the unit will
not be protected. Properly protect and insulate
these pipes from freezing.
Winterizing
If you will not be using your heater for a long
period of time or if the temperatures will drop
below 5º F (-15º C) with the wind chill factor,
turn off your heater and drain the unit of water.
This will keep your unit from freezing and being
damaged. Follow these instructions carefully:
1. Turn off the power supply to the Flash
Water Heater.
2. Turn off the manual gas control valve
located outside your heater.
3. Turn off the manual water shut off valve
located on the water supply line.
